GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 433,644, dated August 5, 1890. Application filed October 17, 1889- Serial No. 327,298. (No model.)

To all whom it may concern.- yoke E is pivoted at one end to the outer end Beitknown that I, OHRIsTOPH.

As shown in the At the upper end of the knotter-frame B a drawings, this device consists of a lug g upon stud or lug 12 projects out from the side opa collar g, which is fastened 011 the shaft. I00

50 posite to that on which the cord-holder is 10- This lug stands just outside of the plane of cated, as seen in Fig. 2 of the drawings. A the upper and lower arms of the yoke and upon its inside carries a small anti-friction roller 9 mounted on a pivot-stud on the in side of the lug and standing in the plane of the upper and lower portions of the yoke. As the shaft is rotated it is evident, therefore, that the roller will be brought alternately in contact with these portions of the yoke, and that when it comes in contact with the upper arm it will raise the yoke on its pivot, and then will depress the same when it strikes its lower arm'. The vibration of the yoke necessary to a proper working of the pawl will thus be produced, it being of course understood that the cam must be arranged on the shaft at such a point that this movement of the yoke will be at the proper time to effect the movement of the cord-holding disk at the instant required. It is evident that this yoke operates as a lever for reciprocating the pawl, and so the construction and arrangement of this device may be modified, so long as it is adapted to operate as a lever vibrated by-the rotation of the shaft.

It is also evident that the construction of the cam on the shaft may be greatly varied, and in fact some other device may be substituted for a cam, provided always that it is adapted to give the proper vibration to the lever by the rotation of the shaft. It will be seen that with these devices I obtain a direct action of the pawl in nearly straight lines and with a Very few pieces, so that the device is very simple and cheap and at the same time is absolutely certain in its operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a graiirbinder, the cord-holder disk provided with a ratchet, in combination wit-h a straight pawl, a lever pivoted to the knotterframe on one side of the latter and on the opposite side connected to the upper end of the pawl and arranged to embrace and enti rely inclose the cam-shaft, and a cam mounted on the cam and gear shaft and arranged to vibrate said lever positively, substantially as and for the purposes specified.

2. The knotter-frame B, provided with the angular bend b in its lower bar, the ratchet c on the cord-holder disk, the pawl F, and the spring f, arranged to bear upon the shoulder formed by the bend b in the frame, substantially as and for the purposes specified.

3. The cam and gear shaft A, in combina tion with the knotter-frame B, provided with a lug lathe yoke E, pivoted at one end to said lug and extended across and embracing and entirely inclosing said shaft, the collar g, secured to said shaft and provided with the lug g, the roller 9 mounted on a stud on the inside of said lug, the spring-pawl F, pivoted to the free end of the yoke, and the ratchet on the notched disk 0, substantially as and for the purpose specified.
